I am not trying to diminish this person's personal experience nor fail to have empathy. However, "incredibly stressed about the state of the world" is itself a sign of poor mental state, and I think that it paradoxically is harmful to make this sort of statement so casually in an an article ostensibly supposed to bring awareness and understanding of states of mind.
If "stress about the state of the world" harms your quality of life, then that, in and of itself, likely means you have a mental disorder, or at least an inability to cope with your own emotions.
Note that I am not talking about being upset about "the state of the world", I am talking about identifying being so upset about "the state of the world" that it harms your daily life.
We normalize extreme emotional reactions too much. It prevents many from understanding that they have an inability to cope with daily life, for whatever reason that may be.
